I made a copy of my wow A and then renamed the original World of Warcraft.
The new copy has been renamed wow A.
Then I moved wow D and wow E back to my C-Drive (faster drive) so all copies are here now.

To be safe, I cut & paste the Cache, Data, Interface and Screenshot folders out of the A-E copies.
That way if necessary they could be restored.

I then SymLinked Cache, Data, Interface and Screenshots from World of Warcraft to A-E.

Keyclone can start the game fine and Shat runs a lot smoother then it was before.
My only issue seems to be modifier keys. Prior to SymLink I could Shift Tilde quickly, for Ghost Wolf on all shaman's; with SymLink if I use a modifier key quickly, half the clients do not pick up the modifier key only the Tilde.
I can easily work around this, by putting combat functions on non-modified keys and less used functions on those that use Alt, Control or Shift.

I'm curious if this is typical for SymLinking.
Shat is much better then it was before, way higher frames per second across my clients.
So I do see very good improvement overall, but have the modifier key or perhaps combination of keys issue.

Any thoughts?
